The iPhone maker is expected to unveil the new iPads and the latest updates to its iMac line, the website said, citing an article published by technology website 9to5Mac earlier this week.

The company plans to unveil the sixth generation of its iPad and the third edition of the iPad mini, as well as its operating system OS X Yosemite, which has undergone a complete visual overhaul, the Internet news website said.

The iPad is expected to have a 9.7 inch screen, while the new version of the iPad mini will have a 7.9 inch screen, Bloomberg earlier reported, citing people familiar with the matter.

Apple also unveiled its Apple Watch, two larger iPhones and a mobile payments service dubbed "Apple Pay" last week.
